Don’t fall for double glazing sales tricks

Man fitting windows

Making massive discounts may be the oldest sales trick in the book – but it’s a tactic that’s still working for the double glazing industry. Is a straightforward quote really too much to ask for?

Given the choice, would you buy a bottle of wine for £4.99, or one that was marked as ‘reduced from £12.99 to £4.99 for today only’? The answer’s obvious to you and me, which is why salesmen use this sneaky tactic to push their products, whether it’s wine or new windows.

Given the double glazing industry’s bad reputation, we wanted to see what really happens when a salesperson visits your home. So we invited 18 reps from the biggest companies to call on our undercover researchers, and recorded their sales patter. We found that 15 of the 18 quoted a high initial price only to cut it dramatically – in many cases, by half. This would clearly leave you with the impression that you’d bagged a bargain.

But have you really bagged a bargain?

Everest offered huge discounts in four out of five of its visits to our undercover researchers – if they signed up on the spot. The biggest ‘saving’ was nearly £17,000. In one of the visits from Anglian, the salesman quoted a high initial price and then admitted, ‘Obviously, you don’t pay this…’ This conversation left us wondering whether anyone pays the first quoted price at all.

The effect of these smoke and mirrors is to leave customers bewildered about what a reasonable price is. And that’s before you take into account dodgy claims about ‘government scrappage scheme’ discounts, for schemes which don’t exist.

Both Anglian and Everest bandied around government funding for discounts, but there isn’t any. So listen out for these claims as they’re a giveaway that your rep isn’t telling the truth.

How to stay savvy

The tactics used by these big firms are the oldest tricks in the book. To stay savvy, go with a firm that’s been recommended by someone you trust, and get three quotes to compare. We recently heard from a customer who’d got the big companies in to quote for his double glazing job – they knocked thousands off their initial prices. But their final quotes were still far more than he ended up paying to a small company that was recommended to him.

We’re pleased to see that a new Double Glazing and Conservatory Ombudsman Scheme has been set up; it’s undoubtedly needed. Still, none of the big players have joined, so it’s a bit of a damp squib. Clearly, there needs to be more accountability for these dodgy sales tactics, so we’ve sent our findings to trading standards officers and asked them to investigate these firms.

Hopefully this will force these companies to understand that we’re not haggling over a bargain buy at the local market. Double glazing is a major investment, and they need to take it seriously.


Our company name is Weatherseal Limited, we registered this name in January 2008, registration number is 06484839. Despite our registration of this name we cannot prevent others from using it as an unregistered name providing, they make it clear it is an unregistered trading as name. e.g. it might be ClearWin Limited t/as Weatherseal, or the Kairos Group UK t/as Weatherseal. These two companies do receive a lot of adverse complaints, they deflect these complaints by calling themselves “Weatherseal,” they are not Weatherseal but ClearWin Ltd t/as, or the Kairos Group Ltd t/as.
Allow me to make this clear, using an alias is not illegal and we are not passing judgement on them, but it is a known fact that they do have many hundreds of clients they have deal with who have written adverse reports about them. My advice is watch out for, and to treat with great caution any window company operating from the premises known as: Unit 7, Road One, Winsford Industrial Estate Winsford, Cheshire. CW7 3PZ. To confuse matters further they have 26 other ‘smokescreen names or t/as aliases trading from this address. A Google search will locate for you a long list of the aliases they are known to have used.
Recently, five companies using this Cheshire address have gone bankrupt leaving a trail of unpaid debts and disgruntled clients who have lost their deposits, two of their other companies are also currently being dissolved. With them using so many different aliases it’s impossible to say group members are good, so do your homework, whoever you choose spend an hour or two researching them especially if they operate from Winsford, Cheshire. Ask for a written quote, do not sign up on the night, wait 7-days, and read the small print. Please remember no handing over huge deposits and do obtain at least 3 estimates.

Lost deposit phoned them i don’t no how many times they told me a lot of lies don’t no how they can sleep at night

My elderly grandmother was well and truly conned by dunraven windows. They pestered her to get an enclosed porch put in and mislead her claiming it would increase the value of the house and would keep the cold out.

They signed her up for a loan with Barclays. It was done where they applied for it and put my grandmother’s details down so repayments come from her account. No way would an 80 year old woman be approved for a 5 year £10,000 loan. All in all with repayments she’s paying £13,000 back which includes interest.

Her house has a main front door but there’s also a side door that leads to the utility area (Tumble dryer, garden storage things etc). The porch is horrendous and isn’t even suitable for the property. It’s a large porch which encloses both the front door and side door but there’s only one door on the porch for entry (directly in front of the main front door).

The huge issue is because of this, it’s now impossible to move things out of the house from the side utility room. So for instance if the tumble dryer needs to be replaced, it literally cannot fit out of the side door down through the porch to the only porch door and outside.

As for the reasons she bought it….. It doesn’t increase the value of the house and certainly doesn’t keep the cold out (in fact it acts like a cold trap where it fills with cold air and feeds it directly into the house).

She’s still got about 3 years of repayments to go and it looks like her money is going to run out before it’s repaid.

Sadly I’m the poor sod who when she’s passed away will inherit the house. The porch will have to be demolished as there’s no other way to move things in and out (no way would a sofa go in or out). So effectively she’s blown £13,000, which is money she could have used to enjoy her retirement more, on something that isn’t fit for purpose and she was mislead into buying.

I used an outfit trading as Green Measures who were to replace a couple of diamond leaded windows. The windoes don’t even match as one has been measured sideways. I have attempted to contact the company but have been lied to on the telephone – it started off with the “van has broken down on the motorway” and “we can’t contact the fitter as he has gone home” I should have read the Google reviews before dealing with them as it appears that any positive ones have been put on by their staff. Unfortunately, the negative resposes to their customer dealing are ringing true. It would have been cheaper to keep the old misted windows and keep the £1900 in the bank. Next time I need double gazing I shall be returning to my trusted local company who have replaced the remaining units. I am currently in communication with Trading Standards with regard to Green Measures

Just wondering if after anyone has had a quote or quick survey, whether their windows started to mist up? Just seems very much of a coincidence that three of ours did. We accepted quote, quite pleased with the salesman and the local company. Still waiting for the work to start as it was due the day after lockdown!

Hi Chrissy – I suggest that you find out what guarantee the company offers. A ten year guarantee is common for new windows and replacement double-glazed panels and some companies offer more. Products seem to have improved but having panels replaced because of misting is still common.
